* Panic instead of return result when adding property This will almost always be unwrapped * Remove unused `set_refcount` function Wasn't valid either way * Add ability to get and set properties on class objects * Updated documentation adding properties |

ext-php-rs
Bindings and abstractions for the Zend API to build PHP extensions natively in Rust.
Example
Export a simple function function hello_world(string $name): string to PHP:
use ext_php_rs::prelude::*;
#[php_function]
pub fn hello_world(name: String) -> String {
format!("Hello, {}!", name)
}
// Required to register the extension with PHP.
#[php_module]
pub fn module(module: ModuleBuilder) -> ModuleBuilder {
module
}
Calling the function from PHP:
var_dump(hello_world("David")); // string(13) "Hello, David!"
For more examples read the library guide.
Features
- Easy to use: The built-in macros can abstract away the need to interact with the Zend API, such as Rust-type function parameter abstracting away interacting with Zend values.
- Lightweight: You don't have to use the built-in helper macros. It's possible to write your own glue code around your own functions.
- Extensible: Implement
IntoZvalandFromZvalfor your own custom types, allowing the type to be used as function parameters and return types.
Goals
Our main goal is to make extension development easier.
- Writing extensions in C can be tedious, and with the Zend APIs limited documentation can be intimidating.
- Rust's modern language features and feature-full standard library are big improvements on C.
- Abstracting away the raw Zend APIs allows extensions to be developed faster and with more confidence.
- Abstractions also allow us to support future (and potentially past) versions of PHP without significant changes to extension code.
Documentation
The library guide can be read here.
The project is documented in-line, so viewing the cargo documentation is the
best resource at the moment.
We are currently unable to deploy our documentation to docs.rs due to the
crate requiring PHP 8.0, which is unavailable in the default Ubuntu
repositories. Documentation can be viewed
here. It is generated from the
latest master branch. Documentation will be moved to docs.rs when Ubuntu
updates its repositories to PHP 8.0.
Requirements
- PHP 8.0 or later
- No support is planned for lower versions.
- Linux or Darwin-based OS
- Rust - no idea which version
- Clang 3.9 or greater
See the following links for the dependency crate requirements:
Usage
This project only works for PHP >= 8.0 (for now). Due to the fact that the PHP extension system relies heavily on C macros (which cannot be exported to Rust easily), structs have to be hard coded in.
Check out one of the example projects:
- ext-skel - Testbed for testing the library. Check out previous commits as well to see what else is possible.
- anonaddy-sequoia - Sequoia encryption PHP extension.
- opus-php - Work-in-progress extension to use the Opus library in PHP.
Contributions
Contributions are very much welcome. I am a novice Rust developer and any suggestions are wanted and welcome. Feel free to file issues and PRs through Github.
Contributions welcome include:
- Documentation expansion (examples in particular!)
- Safety reviews (especially if you have experience with Rust and the Zend API).
- Bug fixes and features.
- Feature requests.
